The Rambam classifies them as "midivrei sofrim v'hem mforashim al ydei 
han'vi'im" (H. Shabbos 30:1,9).  That's one of many examples where the 
Rambam's classification of mitzvos seems less complex than what Hazal 
had in mind.  Ibn Ezra wrote a monograph on this subject (Yesod Mora), 
but I've never seen a serious attempt to analyze the opinions of Hazal 
on this.  Has anyone seen anything about this?
